Guardtime handling in nfs3 differs between 32-bit and 64-bit architectures, and uses the deprecated time_t type.
Change it to using time64_t, which behaves the same way on 64-bit and 32-bit architectures, treating the number as an unsigned 32-bit entity with a range of year 1970 to 2106 consistently, and avoiding the y2038 overflow.
